The resistive temperature probe simulation function can be used with either 2, 3 or 4 wire connection.
As for the resistance simulation function, if a polling acquisition system is used, ensure that the transmitter
carries out the measurement at least 1 ms after the current is present.
B.3.1.5 Thermocouple simulation (temperature)
Display the TRANSMISSION CONFIGURATION dialogue box:
Select the Tc transmission function, then the appropriate "type of thermocouple", using the function and
navigation keys.
Select the display unit
Select the type of cold junction compensation (CJC) used. Enter the temperature of the CJC in the case of a
programmed CJC.
Confirm with ENTER.
The thermocouples available are: K, T, J, E, N, U, L, S, R, B, C, PL, Mo, NiMo/NiCo.
After a significant thermal shock, it is recommended that the unit is left for the temperature to stabilize in order to
use the internal cold junction (CJC) with maximum accuracy.
B.3.1.6 Thermistor simulation
Display TRANSMIT CONFIGURATION dialogue box:
Select Thermistor "transmit function" with function and navigation keys.
Select measurement current (direct or pulsed)
Enter coefficients matching thermistor Coeff. A, Coeff. B and Coeff. C.
Confirm with ENTER.
